SPECIFICATION forming part of Letters Patent No. 774,048, dated November 1, 1904. Application filed July 29, 1902. Serial No. 117,496. (No model.)

To all 'wh/mt it 77mg/ concern:

Be it known that I, CHARLES W. DENIsoN, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented new and useful Improvements in Buddles, of which the following is a specification.

My invention relates to new and useful improvements in buddles for washing the tailings of ore-concentrators and other reductionworks; and the objectis to provide an effective device of simple construction.I large capacity, and which can be operated at slight cost.

A further object is to employ means for rapidly and thoroughly cleaning the device.

Another object is to provide a revolving buddle having a working surface of inexpensive and novel construction, whereby the nest particles of metal deposited thereon are saved.

WV ith the above and other objects in view the invention consists in providing a rotary conical table surrounded by a stationary trough adapted to receive the waste from the table. A duck covering is provided for the table, and means are provided for washing off the concentrates and for cleaning the table.

The invention also consists in providing a novel arrangement of these rotary buddles, each of which is adapted to wash the ore, which is finally discharged in a finished condition.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing one form of my invention, and in which- Figure 1 is an elevation of a buddle constructed in accordance with my invention. Fig. 2 is a plan view of one of the rotary tables of the buddle and its trough. Fig. 3 is a section through the table. Fig. 4is a plan view of one form of table with its duck cover removed. Fig. 5 is a view shoving the manner in which the sections of the duck cover may be cut from a strip of material. Fig. 6 is a plan view of the wash-olf and cleaning sprays. Fig. 7 is a section through the end bearing of the shaft of the tables. F ig. 8 is a front elevation of a spray. Fig. 9 is a side elevation thereof.

Referring to the figures by numerals of reference, 1 is a vertical shaft, bearing at its lower end within a cylindrical boX or step 2, having laterally-extending arms 3, adapted to be secured in any desired manner to horizontal beams or oor-joists 4 and mounted upon a suitable foundation or support. The end bearing of the shaft comprises, preferably, a hardened steel foot 5, fitted in the end of shaft 1 and resting upon a bronze block 6, which is loosely placed and can rotate upon a steel disk or shoe 7, resting loosely upon a lug 8, formed or cast within the inner end of step or cylinder 2. The shaft 1 is preferably tubular, and, as before stated, the foot 5 is adapted to tit securely in the end thereof.

A conical buddle-table is secured to and eX- tends around the shaft 1. This table, as shown in Fig. 4, comprises a rim 9, connected to a hub 10 by means of inclined T-iron beams or spokes 11. V-shaped strips of canvas or ducking 12 are adapted to be secured to the inclined spokes 11 in any suitable manner, and they form the working surface of the buddle-table. These cloth segments 12 are preferably cut from a strip of material in the economical manner shown vin Fig. 5. l/Vooden girths are inserted between the spokes 11 and provided with a wood covering, and

the duck segments 12 extend over this solid table. Inclined T or angle irons 13 are preferably arranged upon the under surface of the table and are secured, by means of suitable braces 14, to horizontal T or angle irons 15. In this manner the table is held rigidly in position upon the shaft 1 and is prevented from sagging. The hub 10 of the table is secured to the shaft 1 in any suitable manner, so that the two will revolve in unison.

A circular stationarytrough 16 is arranged under the outer edge of the table and is provided at opposite sides with outlets 17 and 18, respectively. On each side of one of these outlets 18 is provided a partition 19, and these partitions serve to prevent the contents of is finally washed into the discharge-outlet 35 by the spray 31.

In lieu of arranging the lower table 3() upon the trough 16 from passing outward through said outlet 18, the said circular trough increasing in depth from these partitions to outlet 17 to facilitate the discharge of waste the shaft 1 it can, if desired, be mounted upon material. An inclined spray-pipe 2() is ary a separate shaft adapted to be revolved in ranged above the table and extends from a l unison with the shaft 1. This construction point adjacent to the outlet 18 up to the shaft l would become necessary where the inclined 1. This spray-pipe is supported from a supground upon which the buddle is erected is ply-pipe 21 and is preferably provided with not sufficiently steep to enable the tables to suitable adjustable braces and turnbuclrles 22, be placed at the requisite distance one below whereby the same is adjusted and held rigidly the other. in position. Smaller inclined spray-pipes 23, In the foregoing description I have shown which can be turned and tilted at any angles the preferred form of my invention; but Ido required, are suspended at suitable intervals not limit myself thereto, as I am aware that above the table and are adapted to be used modifications may be made therein without for cleaning the same'. departing from the spirit or sacrificing any Rotary motion is imparted to the shaft 1 of the advantages thereof, and I therefore reand the table secured thereto in any desired serve the right to make all such changes as manner. .Tn Fig. 1 I have shown the shaft fairly fall within the scope of my invention. provided with a large bevel-gear Q11, which is I do not confine myself to the use of duck or driven by a smaller gear 25, mounted upon a canvas; but to suit various conditions any horizontal shaft 26.
